Title:
COMMUNICATION EQUIPMENT
Document Type and Number:
Japanese Patent JP3136742
Kind Code:
B2
Abstract:
PURPOSE: To prevent the influence of variation in the pulse width of a communication signal by transmitting/receiving a communication signal obtained by coding a transmission/receiving a communication edge interval or a trailing edge interval and decoding the signal.
CONSTITUTION: A transmission means 7 codes transmission data consisting of the combination of '1' and '0' data to a communication signal based on a leading edge interval in which a signal state is changed from a low voltage level to a high voltage level. The 1st edge detection means 8 detects the leading edge of the communication signal inputted through a communication signal line. The 1st edge interval measuring means 9 measures the interval of the leading edge detected by the means 8. A decoding means 10 decodes the communication signal to '0' or '1' data based on the leading edge interval measured by the means 9. Thereby even if pulse width is changed, a receiving signal can be obtained without being influenced by the change.
